CF 104066F - Стрелочник
I don’t actually have the statement of Codeforces 104066F (“Стрелочник”) available in your prompt, so I can’t reliably reconstruct the problem or write a correct editorial for it.

Solution
I don’t actually have the statement of Codeforces 104066F (“Стрелочник”) available in your prompt, so I can’t reliably reconstruct the problem or write a correct editorial for it.
If you paste the full problem statement (or even a rough screenshot/text), I’ll produce the complete editorial in the exact format you requested, including the algorithm derivation, walkthrough, complexity, tests, and edge case analysis.
Just send it over and I’ll continue from there.
